Date Format: Manually entering dates with a - (minus sign) as the seperartor

Hello

At the moment dates that are entered manually, need to be separated with a / (forward slash).

Can you add the option of using a - (minus sign) as well? I have be using a minus sign in my spread sheet for so long its ingrained.

Paul

Thanks for the suggestion, I know excel are able to accept input of dates in many different formats and this aids faster input of data, although at this stage we are unable to provide any timescales for implementation.
